Driving the car today and next thing you know it started to sound like I had a small exhaust leak. When I got home I checked and whatever was plugging my thermactor port on my drivers side head must have came out. I cant seem to get any bolts I have laying around to fit and im mildly frustrated. What is the best way to plug these? I have seen the plugs on late model but I cant for the life of me see how I could get those in with the head still on the car. I also dont want to wait 4 days for some $20 plugs.

Same thread pitch as a spark plug.

Knowing that, you can temp use a spark plug, or go down to your local parts store with a plug and match up a threaded plug to it

After doing some searching I did see a few people say it was the same as a spark. I broke off the end of an old plug and I couldn't even ge that in there. I had to just walk away for the day because I started feeling tempted to fill it with jb weld or something lol.

I'm pretty sure that the useful technical thread index has the size and thread pitch of that bolt contained in one of the threads.

Trick Flow sells the plugs that are needed. Even though they are made by Trick Flow they should work in OEM heads. The thread size is 5/8-11

Probably caked with carbon. You'll probably want to see of you can get a wire bore brush or something of the like back there to clean it out?

I think the threads are crossthreaded/buggered. I got a spark plug end started and then it wanted to go in crooked. I didn't really want to hack it up but jb weld is starting to sound like the only way to fix it without removing the head and chasing the original threads with a tap. Oo well kinda sucks but could be worse.
